Drawing on the company’s expertise in crafting extra-thin movements, the Seed VMF 5440 is just 3.4 mm thick. Its robust and sophisticated construction incorporates all the advantages of the tried-and-tested VMF extra-thin calibers. It is wound by a micro-rotor, cleverly integrated into the movement so as to maintain its slim profile.

Deviating from previous designs, the tourbillon is purposefully located at about 7o’clock, clearly distinguishing it from existing VMF Tourbillon movements – the tourbillon of the automatic Seed VMF 3024 and extra-thin hand-wound Seed VMF 5430 are positioned at 6 and 9 o’clock respectively.

To provide an unhindered view of the mechanical ballet taking place, Vaucher Manufacture Fleurier has opted for a flying tourbillon. Mounted on a ceramic ball bearing, the tourbillon cage is made of light-weight titanium for reduced energy consumption and optimal adjustment. The upper part of the cage is made of steel. The tourbillon and cage comprise 67 components for an overall weight of just 0.27 grams.

Like all VMF movements, the Seed VMF 5440 is meticulously finished. Its bridges are laser-engraved with the motif of the gears hidden beneath their surface, showcasing Vaucher’s expertise in laser engraving, marking and machining. The movement finish can of course be adapted to the specifications of each client, offering a high-level of customisability.

The Seed VMF 5440 is available in short series and can be personalized with different options (bridges, cage, micro-rotor, finishing).
